翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrogenolysis ： ウィキペディア英語版 Hydrogenolysis Hydrogenolysis is a chemical reaction whereby a carbon–carbon or carbon–heteroatom single bond is cleaved or undergoes "lysis" by hydrogen.〔Ralph Connor, Homer Adkins. Hydrogenolysis Of Oxygenated Organic Compounds. J. Am. Chem. Soc.; 1932; 54(12); 4678–4690. 〕 The heteroatom may vary, but it usually is oxygen, nitrogen, or sulfur. A related reaction is hydrogenation, where hydrogen is added to the molecule, without cleaving bonds. Usually hydrogenolysis is conducted catalytically using hydrogen gas. ==History== The term "hydrogenolysis" was coined by Carleton Ellis in reference to hydrogenolysis of carbon–carbon bonds.〔〔Carleton Ellis. Hydrogenation of Organic Substances, 3rd ed., Van Nostrand Company, New York, 1930, p. 564 (as referred by Connor and Adkins).〕 Earlier, Sabatier had already observed the hydrogenolysis of benzyl alcohol to toluene,〔Sabatier and Murat. Ann. Chim. () 4, 258, (1915), according to Connor and Adkins.〕 and as early as 1906, Padoa and Ponti had observed the hydrogenolysis of furfuryl alcohol.〔Furfuryl alcohol hydrogenation is accompanied by hydrogenolysis into 2-methylfuran, which gives 2-methyltetrahydrofuran, and further hydrogenolysis opens the ring to give 2-pentanol. Original: Padoa and Ponti. Atti. R. accad. Lincei, 15, () 610 (1906); Gazz. chim. ital. 37, () 105 (1907), according to Kaufmann: W. E. Kaufmann, Roger Adams.

Soc.; 1923; 45(12); 3029–44. 〕 Adkins and Connors were the first to call the carbon–oxygen bond cleavage "hydrogenolysis".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrogenolysis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
